Summary
The PuraMax 2 automatic litter box features a three-layer deodorizing system — sealed waste bin, odor-eliminator attachment, and a citrusy deodorizing spray that fires after every cleaning cycle. It's the most comprehensive built-in deodorizing solution for cat owners who want to eliminate the problem at the source.
A probiotic-based spray that eliminates cat litter odors at the source rather than covering them up. Works on the litter box itself, surrounding carpet, furniture, and anywhere your cat carries smells after using the box.
Pros
- Triple odor control: sealed waste bin + odor-eliminator attachment + automatic citrusy deodorizing spray
- Deodorizing spray fires after every cleaning cycle and randomly throughout the day
- WIRED reviewer noted the box 'smells neutral, dare I say it smells good'
- More affordable than Litter-Robot 4 while offering superior odor control features
- Eliminates odors at the source, not just masks them
- Works on multiple surfaces: litter box, upholstery, carpet
- Effective on cat-carried odors on furniture after litter box use
- Can be incorporated into daily litter cleaning ritual
Cons
- Petkit app is overcrowded with ads for other products
- No sensor to alert when litter is low — must be manually checked
- Deodorizing cartridges require replacement over time, adding ongoing cost
- Requires active application after each scoop — not a passive solution
- Primarily marketed as a stain/odor product, not litter-specific
- May need repeated application for heavily soiled areas
Our take
If you're serious about litter odor, the real answer is attacking it at the source with an automatic box that has deodorizing built in. The PuraMax 2's triple system — including an automatic spray — is the most thorough passive deodorizing setup you can buy without spending $700.
This is the spray that actually solved a real-world litter smell problem for a writer with a sharp nose who had tried everything else. The fact that it works on multiple surfaces — litter box, couch, carpet — makes it genuinely versatile.
